  1. Web Performance Calendar » A Performance Maturity Matrix

    Permalink

    Drawing upon each model, I tried to roughly gauge the perf maturity of organizations, but found I needed a more visual aid — a map of perf work that I would help me identify where orgs are in their perf journey: what areas of performance there are and what level they are in those areas. So I drew up a “Performance Maturity Matrix” with four levels including a “null” level (i.e. lacking the traits of performance maturity) and nine areas of perf work.

    I like Harry’s categorization for performance testing:

    I try to distill the types of testing that we do into three distinct categories: Proactive, Reactive, and Passive.

    I’ve been using “Active” and “Passive” myself and found that it really helps companies better understand why having both synthetic and RUM monitoring in place is important. I really like the way Harry breaks that “Active” category out further based on whether the tests are run proactively or reactively.
